taskhub_task_complete

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the behavioral transparency burden. It does disclose a meaningful behavioral trait: automatically finding the project's completed status using the isCompleted flag and applying it. However, it does not mention side effects, idempotency, error behavior when no completed status exists, or authorization requirements, leaving some behavioral gaps.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two concise sentences. The primary action is front-loaded, and the implementation detail about automatically finding the completed status is added in the second sentence without unnecessary verbosity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with one required parameter, full schema coverage, and no output schema, the description gives sufficient context: it states the purpose and the key internal behavior. Minor gaps include edge cases (e.g., what happens if the task is already completed or no completed status exists), but these do not seriously hinder correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% for the single taskId parameter, so the schema fully documents the parameter. The description does not add extra parameter-level semantics beyond what the schema already provides, so the baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action: 'Mark a task as completed' with a specific resource (task) and a clear effect. It does not explicitly differentiate from sibling tools like taskhub_task_update, though 'complete' is a more specific operation, so it earns a 4 rather than a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no explicit guidance on when to use this tool versus taskhub_task_update, taskhub_task_delete, or other related tools. The phrase 'Automatically finds...' implies a convenience factor, but there is no stated when-to-use/when-not-to-use or alternative selection criteria.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
